Sixth Crusade

The Sixth Crusade was led by the excommunicate Holy Roman Emperor Frederick II, who had repeatedly delayed his own crusading vow across several years before finally undertaking it in person. Rather than winning Jerusalem by force of arms, Frederick, fluent in Arabic and on cordial personal terms with the Ayyubid sultan al-Kamil, whose own attention was divided by his rivalry with his brother al-Mu'azzam over control of Damascus, recovered the holy city almost entirely through personal negotiation rather than battle.

The result was the 1229 Treaty of Jaffa, a ten year truce that returned Jerusalem, Bethlehem and Nazareth to Christian rule for the first time since 1187 while leaving the Temple Mount's own Muslim shrines under continued Islamic administration, an arrangement achieved without a single major battle fought over the holy city itself. The truce held for fifteen years before Jerusalem was retaken by the invading Khwarazmian Turks in 1244, an event that directly prompted the further crusades that followed in its wake. Frederick's own personal fluency in Arabic and his ease in Ayyubid company were themselves unusual among crusader leaders of any generation, and contemporaries noted the contrast with predecessors who had negotiated only through interpreters and intermediaries.

The Sixth Crusade is an unusual case among the numbered crusades in that its own leader spent the entire campaign under papal excommunication, having repeatedly delayed the crusading vow he had taken years earlier before finally setting out for the Holy Land in person. That standing drew sharp criticism from Pope Gregory IX and from the military orders already established in the Holy Land itself, who regarded an excommunicate emperor as an improper figure to lead any holy war at all, whatever he ultimately achieved by negotiation.

Yet Frederick achieved by negotiation what armed campaigns before him had failed to win outright across more than a century of fighting: the return of Jerusalem to Christian rule, secured through a personal relationship with the Ayyubid sultan al-Kamil rather than through the siege warfare earlier crusades had relied on so heavily. The contrast between an excommunicated leader and a bloodless recovery of the holy city remains one of the more striking features historians note about the crusading movement's numbered campaigns as a whole sequence. Frederick's own excommunication was never lifted during the crusade itself, and Pope Gregory IX's hostility toward him continued even after Jerusalem had changed hands, a reminder that recovering the holy city did not by itself settle Frederick's own standing within the church he had defied.
